Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install safe-code-refactoring

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent spots code smells, proposes small reversible transformations and checks that behavior stays the same. You get a step-by-step refactoring plan and the tests to run after each step.
